Why Wind Can Be Stronger at 120m Than at Ground Level

It's a common surprise for new pilots: the wind feels calm standing on the ground, but the drone starts fighting noticeably harder to hold position once it climbs. This isn't a malfunction — it's a real, well-understood atmospheric effect, and it's specifically why UAV Meteo shows wind at four different heights instead of just one.

The atmospheric boundary layer

Near the ground, friction from terrain, buildings, trees, and other obstructions slows the wind down — this zone is called the atmospheric boundary layer, and it typically extends anywhere from a few hundred meters to around a kilometer up, depending on terrain roughness and atmospheric stability. Within it, wind speed generally increases with height, sometimes substantially, because there's progressively less surface friction to slow it down.

This is why a standard ground weather station measures wind at exactly 10 meters above ground — high enough to be somewhat clear of the most extreme surface friction (grass, small obstacles), but still fully within the boundary layer, not representative of wind at 80 or 120 meters.

What this means for your flight

If your flight plan involves climbing to 100+ meters — common for aerial photography, mapping, or long-range flights — the wind you feel at your feet during preflight checks is not a reliable predictor of what your drone will experience once airborne. In some conditions (strong low-level friction, a light near-surface breeze with a much stronger flow just above it), the difference between 10m and 120m can be dramatic.

Wind direction can shift with altitude too, sometimes independently of speed — this is called wind shear, and it's a second, separate reason ground-level observation alone isn't enough for a climbing flight.

What UAV Meteo actually shows

The Wind by Altitude panel on the home page shows real modeled wind speed and direction at 10m, 80m, 120m, and 180m — not an estimate or an interpolation, but genuine data at each of those four heights from the underlying weather model. These are also the only four heights the model distinctly represents for a given location; that's why the panel doesn't offer arbitrary heights like 50m or 150m.

Each row includes a rotating arrow showing the wind direction at that specific height, so you can see both the speed and the direction changing together as you look up the panel.

One limitation worth knowing: gust data is only published at 10m by the underlying weather model, not at the higher altitudes — so the Wind by Altitude panel intentionally shows only speed and direction at 80/120/180m, without a gust figure there. See Wind Speed vs Gusts: What Drone Pilots Need to Know for why gusts matter and where to find the 10m figure.

Planning around it

If you're climbing well above 10m, check the Wind by Altitude panel before you fly, not just the headline Wind Speed card — and factor in that stronger wind at altitude affects your return-to-home battery margin, since flying back against a headwind you didn't expect burns more battery than the outbound leg.
